92 OPHIDIA. 
Each subcaudal black in front. Specimens from Jalisco have the abdomen largely 
marbled with black. 
8. Geophis redimita. 
Geagras redimitus, Cope, Journ. Ac. N. Se. Phil. 1876, p. 141. 
Sphenocalamus lineolatus, Fisch. Oster Programm Akad. Gymnas. Hamburg, 1883, figg. 3-5. 
Hab. Mexico, Mazatlan (Mus. Hamburg), Tehuantepec (Sumichrast). 
Head rather narrow, not distinct from neck, tail short; eye of moderate size, with 
round pupil. Snout depressed, projecting beyond the lower jaw, the rostral shield 
being broad in froyt, with a sharp edge. Anterior frontals narrow ; vertical six-sided ; 
supraocular well developed ; one ante- and one postocular ; five upper labials, of which 
the third only enters the orbit; the fourth is in contact with the occipital, separating 
the elongate temporal from the postocular. The first pair of lower labials do not meet 
in the median line; anterior chin-shields at least twice as large as posterior. Scales 
smooth, in fifteen rows. Ventrals 118 or 119; anal divided; subcaudals 25 or 30. 
Upper parts of a pale ground-colour, with narrow brown lines along the series of scales ; 
head brown above, with a whitish longitudinal band on each side running from the 
rostral to the end of the occipital. | 
B. Species with the occipital separated from the upper labials by a temporal. 
9. Geophis omiltemana, sp.n. (Tab. XXXIIL. fig. A.) 
Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith). 
Head broad, short, and depressed, body and tail of moderate length. Eye rather 
small, with the pupil subelliptical. Anterior frontals well developed, one-fifth or 
one-sixth the size of posterior. Vertical broader than long, six-sided, with the anterior 
angle very obtuse, the posterior being a right one; its lateral edges are very short, 
convergent; supraocular rather small. Six upper labials, the third and fourth entering 
the orbit, but it is worthy of notice that a small portion of the third upper labial is 
separate, and forms a small preocular below the preocular proper; the sixth is the 
largest, and separated from the occipital by a large temporal, which is in contact with 
two postoculars. ‘The first pair of lower labials form a suture together; anterior chin- 
shields not much larger than posterior. Scales in seventeen rows, of which only the 
two middle ones show a faint carination. Ventrals 152, anal entire, subcaudals 52. 
Upper parts black with narrow whitish cross-bars, of which the three or four anterior 
are more distinct than the following, and are dilated on the sides as they merge into 
the white coloration of the abdomen. The cross-bands of the middle and posterior 
parts of the body are very indistinct and placed in pairs. 
One specimen, apparently a male, is 115 inches long, of which the tail takes 24 
inches; two other specimens are of smaller size.
